GATE.

SPECIFICATION forming part of Letters Patent No. 582,826, dated May 18,1897. Application filed December 17,1896. Serial No- 615,994. (Nomodel.)

To all whom it 'IILU/Z/ concern.-

Be it known that I, LEVI LUNDQUIST, a citizen of the United States,residing at Middletown,county of Lake, State of California, haveinvented an Improvement in Gates; and I hereby declare the following tobe a full, clear, and exact description of the same.

My invention relates to that class of gates which are adapted to bereadily opened and closed by the approaching or receding travelerwithout requiring him to alight from his vehicle or conveyance.

My invention consists in the hereinafterdescribed sliding gate with theoperatingropes, in combination with the locking mechanism adapted to beoperated by said ropes, as well as to be operated by hand when thetraveler is on foot.

The object of my invention is to provide means for opening and closingthe gate and at the same time operating the lock thereof, said meansbeing so located as to be most conveniently reached by the traveler inapproaching the gate from either direction, so that he may both open andclose the gate from the right-hand side in whichever direction he may begoing.

Referring to the accompanying drawings, Figure 1 is an elevation of mygate. Fig. 2 is a plan of the same, the roof or hood M being brokenaway.

A is the roadway. On one side of the roadway is a post B, and on theother side is a two-part or slotted post 0, while beyond and in the lineof the two posts is a third post D. These posts carry at their tops thebeam E, on which is supported the track F.

G is the gate, having end standards g, the tops of which are forked andpass up on each side of the beam E and carry in their tops the rollersH, which rest and travel upon the track F and by which the entire gateis supported.

The gate plays back and forth through the two-part or slotted post G.IVhen in position closing the roadway, its end standard comes up intocontact with the post 13, and when over to the other side its other endstandard comes up against the post D. Within the forked top of one ofthe gate-standards g is fixed a catch-lug N.

Pivoted to the track-beam E is a gravity latch-bar O, the lower end ofwhich hangs down normally in the path of the catch-lug N, so that thegate in closing will carry the catch-lug under the gravity latch-bar andpast it, and the latch-bar will then drop down behind said lug andengage, it so that the gate is thus locked in a closed position and canbe freed only by lifting the latch-bar from its engagement with thecatch-lug. To effect this release, I have pivoted to the gate-standard ga swinging lifter P in the shape of a bail, said lifter being controlledby a spring This lifter acts directly under the latchbar and will liftsaid bar to free it from the catch-lug and allow it to drop by gravityto its position again.

I, J, K, and L are posts on each side of the gate. These are located ateach side of the roadway and are four in number, two being on one sideof the gate and two 011 the other.

Attached to the lifter P, and thence extendin g upwardly to the standard9 of the gate and around a guide-pulley g thereon, is a rope or cord 2,which thence extends over to the middle post C and around a guide sheaveor block 1'' thereon, thence back again to the post B and around a guidesheave or block I? thereon, and thence to a guide sheavc'or block F,supported by the post I, said rope or cord hanging down within reach andweighted, as shown. Secured to the other end standard of the gate is arope or cord j, which thence passes to and around a guide sheave orpulley j on the center post 0, and thence to a guide sheave or pulleyon' the post J, its end hanging down within reach I and weighted.Connected with the other side of the first end standard g of the gate isa rope or cord k, which thence extends to and around a guide sheave orpulley 70 on the post B, and thence to a guide sheave or pulley k on thepost K, hanging down within reach and weighted. Secured to the lifter Pand thence passing up and over a pulley g on the first end standard ofthe gate is a cord or rope Z, which thence passes to and around a guidesheave or block Z on the center post 0, and thence to a guide sheave orblock Z on the post L, from which it hangs down within reach and is alsoweighted.

The operation is as follows: Approaching the gate the traveler pullsupon the right-hand rope. This being connected with the litter P firstraises said litter and causes it to liftthe latch-bar 0 from itsengagement with the catch-lug N. The gate being free continued pullingon the rope causes said gate to slide open. Passing through the travelerpulls on the right-hand rope and thus closes the gate, whichautomatically locks.

In order to open the gate by hand, I have provided a hand-cord Q,depending from rope 2 This is guided downwardly to within reach and maybe taken hold of from either side of the gate. A pull down on rope Qwill raise the lifter P and the latch-bar 0, thus unlocking the gate,which may then be slid over by hand. Thus by this arrangement of ropesthe gate can be moved from side to side to open and close the roadway.The advantage of this arrangement lies in the fact of having four ropes,two of which extend from opposite sides of the gate to posts on theother side of the roadway. The object of this is to enable the gate tobe operated from the right-hand side no matter in which direction thetraveler may be approaching. Consequently the ropes which are to hisright as heapproaches the gate from either direction are those which arearranged to pull the gate open, and those which are upon his right as herecedes from the gate in either direction are arranged to pull the gateclosed. This arrangement is a most complete one and results in an easeof operation not to be had in those gates where the pulling devices arearranged, as usual, only upon one side of the gate, whereby althoughapproaching and.receding in one direction the pulling devices areconveniently located, yet in the other direction they are inconvenientlylocated.

M is a roof-shaped protector or hood over track F. It is supported onbrackets m, secured to the postsB and D, and is adapted to form acovering over the rollers of the gate and the track on which they run,thereby keeping these parts protected from weather and keeping themcleaner and dryer than otherwise.

G are guides extending between the posts, and H is a roller under theend standard g of the gate. The guides and roller are very useful forheavy gates and to hold the gates in place during heavy winds.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a gate, the overhead track and the gate having rollers whereby itis suspended from and is adapted to travel on said track in opening andclosing, in combination with a catch-lug fixed in the upper portion ofthe gate, a gravity latch-bar hanging from the overhead track andadapted to engage said catch-lug to lock the gate, and a swinging liftercarried by the gate and adapted to operate under the latch-bar to liftit from its engagement with the catch-1n g and free the gate.

2. In a gate, the overhead track and the gate having rollers whereby itis suspended from and is adapted to travel on said track in opening andclosing, in combination with a catch-lug fixed in the upper portion ofthe gate, a gravity latch-bar hanging from the overhead track andadapted to engage said catch-lug to lock the gate, a swinging liftercarried by the gate and adapted to operate under the latch-bar to liftit from its engagement with the catch-lug and free the gate, and a ropeconnected with the lifter to operate it. I

3. In a gate, the overhead track and the gate having rollers whereby itis suspended from and is adapted to travel on said track in opening andclosing, in combination with a catch-lug fixed in the upper portion ofthe gate, a gravity latch-bar hanging from the overhead track andadapted to engage said catch-lug to lock the gate, a swinging liftercarried by the gate and adapted to operate under the latch-bar to liftit from its engagement with the catch-lug and free the gate, ropes orlines attached to said lifter and connected with the gate whereby whenpulled upon, the litter is operated to free the gate, and the latter isslid open, and ropes or lines connected with the gate for closing itagain.

l. In a gate, the overhead track and the gate having rollers whereby itis suspended from and is adapted to travel 011 said track in opening andclosing, in combination with a catch-lug fixed in the upper portion ofthe gate, a gravity latch-bar hanging from the overhead track andadapted to engage said catch-lug to lock the gate, a swinging liftercarried by the gate and adapted to operate under the latch-bar to littit from its engagement with the catch-lug and free the gate, and fourropes or lines having each one end connected with the gate, two of saidropes or lines, one on each side of the gate being for closing the gate,and the other two for opening it, said last-named being also connectedwith the lifter whereby the latch-bar is released preliminarily toopening the gate, said ropes or lines being properly guided to fourposts on opposite sides of the roadway and gate whereby they areconveniently located for a traveler approaching or receding in eitherdirection.

In witness whereof I have hereunto set my hand.

LEVI LUNDQUIST.
